About ChatMCP

ChatMCP is an AI chat client that implements the Model Context Protocol, the standard used to connect language models to external tools and data. It is built with Flutter and Dart, so the same app runs on macOS, Windows, Linux, iOS, Android, and the web. It is released under the Apache-2.0 license.

Installers are provided through GitHub releases for desktop and Android, an iOS build through TestFlight, and a web version hosted on GitHub Pages. The README notes Linux runtime requirements for AppImage and DEB packages on Ubuntu 22.04 and 24.04, and mentions improvements such as better dark theme support and unified data storage in recent versions. Documentation is available in English, Chinese, and Turkish.

ChatMCP suits developers and enthusiasts who want a single graphical client for trying MCP servers with the language model of their choice, rather than using a command-line host. It is a client application, so there is no server component to host.
